IMPROVEMENT IN SHUTTER AND WINDOW FASTENERS.

Specification formingpart of Letters Patent No. 157,226, dated November24,1874; application filed October 10, 1874.

To all whomit may concern Be it known that I, JOHN G. RYGKMAN, ofPhiladelphia, in the county of Philadelphia and'State of Pennsylvania,have invented a certain new and useful Shutter and Window- Sash Lock;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification, in which-Figure 1 is a perspective, and Fig. 2 a vertical sectional, view of myinvention. Fig. 3 is a perspective view, showing the application of thefastener to the sash.

The object of my invention is to provide an attachment fora window-sashby which the same may be securely fastened against burglariousintruders, and which will serve at the same time for a lock for theshutters, both when opened and closed. My invention consists in thenovel construction and combination of parts, as hereinafter fullydescribed and claimed.

In carrying my invention into effect, I provide the shutters with twospring-dogs, having each lips on opposite sides, for engagingalternately with a fastening in the wall or a shoulder in thelock-plate, according as the shutters may be opened or closed. On theunder side of the lower piece of the upper sash is secured a metalplate, (the lock-plate above mentioned,) in the center of which is apivoted button of elongated form. When this button is turnedtransversely of the look-plate the shutter catches or dogs may be drawntoward each other. When said button is turned at right angles to atransverse position, or longitudinally of the lock-plate, thespring-catches are impinged by it against the shoulders alreadymentioned, and cannot be drawn together. The pivot of the button iselongated sufficiently to pass through to the upper side of thesash-piece, where it finds a bearing in a recessed plate secured byscrews to said upper side of the sash-piece. Beneath this plate is ashort lever, attached to the pivot, so that, when moved, the buttonbelow will be turned transversely or longitudinally with reference tothe lock-plate, as already described. The

outer extremity of this lever is provided with a loose pin, which may beraised to allow the end of the lever to pass over the sash-piece, andwhich, when dropped, will prevent said lever from being turned.

Referring to the accompanying drawing, A represents a lock-platedesigned to be fastened by screws to the under side of the lower pieceof the upper sash of a window. A A are cleats or flanges at each end,fashioned with shoulders a a, for the engagement of the springcatches ordogs B. These catches B B are pivoted in metal plates 0 0, attached tothe shutters, having lips b b on opposite sides and springs 12 b, bywhich they are forced into the requisite engagement with the fasteningsin the sash or wall. D is 'an elongated button, pivoted centrally in thelock-plate A. When turned longitudinally on the plate A, it looks thecatches B B in engagement with the shoulders a a. When turnedtransversely with reference to said plate it offers no bar to themovement of said catches, which may be then drawn toward each other torelease their contact with said shoulders. The pivot D of said button isextended sufficiently to permit its passage clear through the lowerpiece E of the sash and find a bearing in the plate F on the upper sideof the latter. G is a short lever, secured to the pivot D, and made ofsufficient length to extend over the lower sash E, so that its loose pin9 may drop inside said sash, and thus prevent the lever from beingturned.

The operation of the device is as follows:

When the shutters are opened the outer lips of the dogs B will engagewith suitable retaining-pieces fastened in the wall of the house. Whenthe shutters are brought to, to close them, the button D being thenarranged transversely of the lock-plate A, the catches will engage, asshown, with the shoulders at a. The leverGr is then moved until itsextremity passes outside of the sash E, permitting the loose pin 9 todrop, this movement turning the button D so as to fasten the catches byimpinging upon them, as already described. To unlock the device, the pin9 is first raised and the lever G moved ,till it is parallel with thesash E and clear of the sash E, this movement turning the button Dtransversely of the plate A. The inner sash E is then to be raised andthe catches B B cleared of their engagement with the shoulders (I. a,this being readily effected with one hand by the person opening thewindow. As soon as the catches clear the shoulders at a the shutters maybe pushed open, when the outer lip of the catches will engage, asalready described, with retaining devices in the wall of the house.

The sashes, irrespective of the shutters, may be firmly locked in aclosed position by turning the lever G, as already described, over thesash E until its loose pin drops down inside said sash, as above setforth. 7

For some sashes one end of the plate F may have a configuration toadaptit to the moldin g, against which it is desirable, both for the
